Embodiment Construction

[0018] In order to make the purpose, technical solution and advantages of the present application clearer, some embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, not to limit the present application.

[0019] The first embodiment of the present application relates to a method for updating a map, which is applied to a terminal or a cloud. Terminals can be intelligent robots, unmanned vehicles, navigation devices for the blind, etc. The cloud communicates with the terminal to provide the terminal with a map for positioning or directly provide the terminal with a positioning result. This embodiment uses a terminal as an example to illustrate the execution process of the map update method, and the process of executing the map update method on the cloud can refer to the c...

Abstract

Embodiments of the present application provide a map update method and device, a terminal, and a computer readable storage medium. The method is applied to the terminal or the cloud, and includes thefollowing steps: acquiring indication information of a first map, wherein the indication information of the first map is used to indicate the establishment duration of the first map, and / or is used toindicate the location success probability of the first map; comparing the indication information of the first map with preset information, and updating the first map according to the comparison result.

Description

technical field [0001] The present application relates to the field of computer vision, and in particular to a map updating method, device, terminal and computer-readable storage medium. Background technique [0002] If an intelligent robot or unmanned vehicle wants to complete some simple or complex functions in an unknown environment, it needs to know the map information of the entire unknown environment. By obtaining the information of the unknown environment, a map of the unknown environment is established for the positioning of intelligent robots or unmanned vehicles. Only successful mapping and positioning can guarantee the navigation and other functions of intelligent robots. At present, the mapping and positioning methods generally collect maps manually. Due to the change of the scene, the positioning effect of the previously collected map may become worse, and the positioning success rate may decrease. If you use a map with a low positioning success rate for posi...
